CUFF BUTTON.

Application filed February 25, 1924. Serial No. 694,840.

tons, of which the following is a specification.

This invention relates generally to cuff buttons, but more particularlyto that type constructed of separable sections.

Itis chief object is to provide a cuff button of this character havingsimple and reliable means for separably connecting the sections of thebutton.

Another object of the invention is to provide a separable cuff buttonwhose sections are connected and disconnected by a turning movement ofone section relative to the other and in which a dual locking device isemployed for positively preventing the sections from accidentallypulling apart and also for resisting the relative turning movement ofthe sections.

In the accompanying drawings:

Figure 1 is a transverse vertical section o-n line 1-1, Fig. 2. Figure 2is a transverse vertical section on line 2 2, Fig. 1. Figures 3 and 4:are horizontal sections on the correspondingly numbered lines in Figs. 1and 2, respectively. Figure 5 is a perspective view of the lockingdevice or spring plate which forms a. part ofthe socket member of thebutton. Figure 6 is a horizontal section on line 6 6, Fig. 1.

Similar characters of reference indicate corresponding views. y

The improved button consists of separable sections 10, 11, which are ofsubstantially the same shape, one constituting the stud member and theother constituting the socket member. Each of these members ispreferably provided with a hollow head 12 and a flanged base 13connected therewith by a neck 14 having an opening 15 leading to theinterior of said head.

Thest-ud member is provided with a shank or round post 16 which issuitably `secured in the opening 15 thereof and which is adapted toenter the corresponding opening in the socket member 11 for detachablyconnecting said members. The outer or upper end of this post terminatesin a reduced {iat-sided head 17 of conical form between which and theround portion of the post are parts throughout the several.

formed o-pposit-ely-facing locking notches or grooves 1S. In the closedposition of the button sections, this head extends into the hollowportion 12 of the socket section.

Arranged within the hollow head of the socket member 11 is a lockingdevice, preferably in the form of a plate 19, constructed of sheet metalor similar material, which is held' against turning in, said member andwith which the post 16 of the stud member is adapted to interlock uponinserting it into the socket member and turning one of said members afraction of a revolution. For this purpose, the locking plate isdisposed horizontally in the socket member head and extends across itsneck-opening 15, the same being provided with a. substantiallyrectangular opening in line with said neckopening and o-f a size toreceive the reduced post-head 17 when turned into register therewith.Ihen the stud member is turned to bring its post-head out of registerwith or at approximately right angles to the plateopening, the notches18 thereof interlock with the opposing marginal edges of said openingand prevent separation of the button-sections. As shown in Fig'. 1, theplate 19 rests on the bottom of the socket member head 12 and may beprovided at its ends with inclined extensions 21 which engage the sidewalls of said head. In the embodiment of the invention shown in thedrawings, this locking plate is securely held in place by clamping itbetween the marginal rim of the head and its top piece 22.

Means are also provided for yieldingly resisting turning of the studmember relative to the socket member after they are assembled or broughtinto locking engagement. These means are preferably made an integralpart of the plate 19 and consist of opposing spring jaws 23 bent out ofthe central portion of this plate on either side of its opening 20. Assho-wn in Figs. 1 and 5, these jaws are curved upwardly and thencedownwardly and bear against the opposite f'lat sides of the post-head 17to resist movement `of the lattereout of its locked ,position. Toprevent the jaws from being deflected laterally during the relativeturning movement of the stud member and socket member, their free orlower ends 2-1 extend into the plate-opening 20, as clearly shown inFig. 5.

While the post 16 may be securely. fartened to its stud member 10 in anywell known manner, we prefer to mount it in the nianner shown in Figs. 1and 2. As there shown, the post is provided at its lower end with areduced head 25 having -notches in its opposite sides. Secured wit-hinthe hollow head-portion 12 of the stud member is a plate 27 having arectangular opening 2S With the opposing marginaledges oit' `which thep0st head notches 26 are adapted to interlock to preventlongitudinaldisplacement of said post relative to the stud n'iember. Tohold vthe post against turning, th'e plate 27 is provided withoppositely-'r'acing jaws or tongues 29 which are 'adapted to 'extendinto the plate-opening' 28' :torA engagement with the 'lat sides of thepost-head. These ,jaws are preferably 'formed integral "with said plateand possess the required flexibility to permit them to springdownwardly'when Ethe post-head is inserted in the plate-opei'iing whileassembling the parts, after which they are forced backward to a'substantially horizontal position with their opposing ends abut-tingfirmly against the sides ot the posthead, as shown in Fig. 1.

vTo prevent the post 16 being lforced downwardly 'into the head or the'stud member, the same 'is `provided intermediate its ends with anannular shoulder which bears at its underside against vtheopposing'tlared end o'tA the neck-opening 15.

In use, the post or 4the s'tud member l0 is inserted through theneck-opening oit' vthe socket member 11 with its head 1T in position toenter the 'rectangular opening 20 or the locking plate 19. yThe studmember is then given a. quarter turn to bring its head transversely ofthe plate-opening and its notches 18 into locking engage'n'ient with thelatter. During this operation'the spring jaws are at first spreadoutwardly aiidthen sprung inwardly or toward each other against theflat-sides or the postfhead. In 'this position, the two parts 'oit thebutton are reliabfly and positively locked against accidentalseparation. To separatet'he button n'lembers, one of them is simplygiven a quarter turn relative lto the other to bring the post-head 17longitudinally in line with the vplalteopening 20, whereupon the studmember can lbe readily withdrawn from the socket men'iber.
